' Specification of Letters'lPatent.

Application l'ed June 23, 1911. Serial No. 635,019.

T all whom .it may` concern -Be 'it'known that I, CHARLES Smm-.Bend

.a -citizen ofthe United States, residing in Toledo, in the county ofLucas and State of Uhio, have invented /af new and useful Tmprovement inscrevta'p VNozzles for Cans, of which the following is a-specication.

This invention relates to an improvement in screw caps for can nozzles,and it consists in certain novel features of construction set forth andclaimed herein..

In the accompanying drawing which forms a part of this specification,Figure 1 screw caps. Fig. 2 is a top or plan View of the same. Fig. 3isa vertical section on the likewise ianged with a flange b.

line 3-3 of Fig. 1, and Fig. 4 is a sectional view of the body and topof the nozzle, before the same are united together.

lln said drawing Airepresents the tubular seamless body of the cap,screw threaded as at a to t the correspondingly screw threaded lcannozzle,-not shown,-and made with an outwardly'tlanged upper edge a1. v

Bis the countersunk top of the nozlzle,

he countersunk top -B is crowded into the upper end of the screwthreaded body A- and the two seamed together by folding the top flange baround and under the body Hange a. This makes an extended rounded 'andremoving the cap. The usual notches lD D are cut in the two-partvertical portion,

. to receive an opening bar or tool, in case the screw cap is tootightly applied to be closed or opened by the fingers alone.

E represents theordinary disk of cork or other resilient packingmaterial inserted to aid the closure.

As clearly shown in Figs. 3 and 4 the'slots formed in the countersunktop B of the screw`cap do not extend to the periphery thereof butterminate within the circumference of-the flange b so that the latter isnot unnecessarily weakened. lVith this construction when the flanges a1and b are rolled to formv the external bead, the latter is relativelystrong and rigid and well adapted toresist the strains put upon itV whena tool is employed for unscrewing the cap.

Having described the invention, claim is made as follows:

A sheet metal screw cap for can nozzles,

- consisting of a tubular screw threaded seamless body having anoutwardly flanged upper edge; and a countersunk top having itscountersunk portion crowded into the top of the body, and having a topflange which is longer than the flange of the body, and seamed outwardand downward around and under the body flange, this flange being nurledon its exterior surface and the flange of the top and the Hange of thesaid body being cut across toform notches which overhang and are onlines outside of the said body.
